MARKING DEVICE. I

Specification of Letters Patent. Patented Oct. 26, 1920.

Original application filed October 8, 1915, Serial No.,54,828 Divided and this application filed March 16,

Further objects and advantages of the invention will be apparentfrom the detailed description thereof contained hereinafter, in which I have described one embodiment of theinvention, which is to be considered merely as illustrative of many other'embodiments within the principle thereof. In the drawings;

Figure 1 is a side viewof a portion of a machine containing a marking device made.

according to my invention;

Fig. 2 is a central section of such machine taken parallel with the plane of Fig. 1; Fig. 3 is a view'of the marking device shown detached, certain of its parts being in section, and

Fig. 4 isa section on line 4-4,, Fig. 4 3,

looking in the direction of the arrows.

Although the marking device may be used in connection with any desired machine for operating upon webs of paper or similar material, it is particularly adapted to be used in connection'with a machine such as is disclosed in my co-pending application, Se-

entitled, Paper interfolding machine, of which application the present case is a division.

In the drawings I have shown a portion of the frame of a machine, 1, which supports rolls 2 and 3 upon shafts 4 and 5 respectively. Gear 6 upon shaft 4 is driven from parts of the machine not shown, or in any 'other desired manner, and meshes with gear 7, which latter rotates the roll 3. These rolls are designed to perform any desired operations upon a web of paper or similar material, and will not be described in detail; as their specific construction is not material.

to this invention.

1918. Serial No, 222,858.

The marking device is located in the pathofthe web before it reaches the rolls 2 and 3, and is intended to indicate upon the web when predetermined lengths of the same have been operated upon by therolls. For this purpose the web A is fed into the machine between a printing bed roll 7 mounted upon ashaft 8, and a printing cylinder 9, which latter is mounted upon a shaft 10. The web then passesover a feeding roll'11 mounted upon a shaft 12, atension roll 13 supported upon an arm 14, carried. by a shaft 15, being provided to. press the web against the surface of feeding roll 11/ From this point the. web passes to roll 2 where it is operated upon as above de-' scribed.

p The marking mechanismmay conveniently be actuated by provid ng a gear 16 upon shaft 12wh1ch meshes -w1th gear 6, and

which also meshes 'with'a gear 17 upon "a shaft 8 which carries the printing bed roll 7 A further gear 18 carried by shaft 10 transmits motion from shaft 8 to the shaft 19. which carries the printingcylinder 9. i

In order to actuate the marker, later to be described, I have employed the following mechanism, the details of which, however, arenot essential. Gear 17 is provided with a hunting tooth 19 which is secured preferably to the, face of said gear by means of a screw 20' andapin' 21." The gear 18, on

the other hand, is provided with a movable slide 22, having a projection 23 adapted to be engaged by tooth 19 hereinafter described. The slide 22 has furthermore a I 7 longitudinal slot 24 which receives .oneend rial No. 54,828, filed October 8th, 1915, and

of a lever 25, which lever is: held in position upon shaft 10 by means of'a' clamp 26. The

other end'of the lever 25 rests beneath a marker 27 in a recess 28 in the printing cylinder'9, which marker 27 is normally held in. retracted position by a spring 29. A plate 30, held in place by screws 31 maybe provided to hold removably in place the marker 27 and spring 29. An inking roll 32 on an over the bed roll 7 For instance, the gear thereof, and tooth 19 will engage projection 23 once every seventy-five revolutions.

Slide 22 and its projection 23 are normally pressed into outer position by spring 29, and the marker 27 is at the same time held in retracted position. When tooth 19 engages the projection 23, slide 22 is pushed thereby into its inner position, and lever 25 istilted to advance marker 27 into a position to engage the web as the latter passes over bed roll '7 It Will be apparent that by changing the ratio of gears 17 and 18, any desired lengths of the: Web may be periodically marked off in a similar manner.

While I have described my invention above in detail it is obvious that many changes may be made therein without departing from its spirit as defined in the appended claims.

I claim: V a

1. A marking device comprising a bed roll for receiving a Web of material to be marked, a rotating printing. cylinder adj acentthere to, a marker reciprocably mounted upon said cylinder and normally held in retracted position, intermesh'ing gears for rotating the bed roll and the printing cylinder and c0- operating members respectively carriedby said gears periodically engaging to advance said marker into position to contact with the Web. I 2. A marking device comprising a printing bed roll for receiving a'web of material to. bemarked, aprinting cylinder androll, said cylinder and'roll being mounted upon adjacent shafts, a marker reciprocably mounted upon said cylinder, means for rotating said shafts and a device carried by one of said means for periodically moving said marker into position to contact with the Web. 7 i V 3. marking device comprising a bed roll for receiving a Web of material to be marked, a marker, said-roll and marker being mounted upon adjacent shafts, intermeshing gears on said shafts for driving the bed, roll and the marker, and means on said cooperating gears for moving said marker into position to contact With said Web when a certain point on one gear engages a certain point on the other. 1

4. A marking device comprising a bed roll for receiving a Web of material to be marked, a marker, said roll and marker being mounted upon adjacent shafts, intermeshing gears upon said shafts, a hunting tooth on one of said gears, and a cam device upon the other gear connected to said marker, and adapted to be actuated by said tooth to advance the marker into position to contact With the Web.

5. A marking device comprising a bed roll for receiving a Web of, material to be marked, a shaft adjacent thereto, gears for driving said roll and shaft,and means carr'ied by said driving gears for periodically V marking the Web as it passes over the roll.

6. A marking device comprising a bed roll adapted to receive a Web of material to be marked, a shaft adjacent thereto, gears respectively for driving the roll and shaft, said roll gear having a tooth, a-movable slide on the shaft gear adapted to be engaged by said 7 tooth, and a marker actuated from said slide.

7. A. marking device comprising a print 111g cylinder having a marker reciprocably mounted therein and normally'held in retracted position, a slide reciprocably mounted adjacent such member, a lever engaging both said slide and marker, means for periodically moving said slide to actuate the lever and advance the marker, and means for passing a Web of material over said printing cylinder. a

8. A markingdevice comprising a printing cylinder having a marker reciprocably have hereunto set myhand.
